Hi there. First off I want to say thanks for this plugin and the functionality behind it. It really is amazing. Oh and it does work with WP 3.6.1 and the Twentythirteen theme in case anyone wonders.
So I've been working with this plugin today, looking at the code, learning the ins and outs. I'm pretty confidant that I can explain what the options do. In tinkering with the source code today, I got to thinking that it would be nice to show business listings underneath the categories they are assigned to respectively. Think of a kind of hierarchical navigation menu where the title represents a top-level link or in this case a category and the sub-level links are the businesses. I'm more than comfortable working with PHP as it's what I do.
My problem is that I just don't know which of the plugin's functions to put on businessdirectory-main-page.tpl.php Is what I'm talking about possible with this version? Oh and I'm using version 3.1.1 of the plugin.
